LV102 Manual










































The LV102 Power Station

The 5 amp LV102 is built to the new RP-9.1.2 specifications.

The LV102 has programmable DCC track voltages (form 11 volts DCC to 22 volts DCC in 1/2 volt increments, and is equipped with a RP-9.3.1 (revised) cutout for use with RailCom.

The LV102 is an opto-isolated power station for safety and is built to support all forms of DCC layout wiring including common rail and 2 rail wiring (direct home wiring).

We have changed the rating of our power stations to reflect use in typical environments with typical transformers.

The LV102 has a current rating of 5 amps, 4.4 amps continuous at 50 degrees C

What does this amp rating mean?

For safety the temperature of the case must not exceed 50 degrees Celsius. This is a safety requirement required for CE which we conform to.

As a power station is used for extended periods at a high amperage, the case heats up. The thermal protection in the unit is designed to shut down before the case reaches 50 degrees C.

You can maximize the current rating by using a transformer that is well matched for the desired DCC track voltage.

·     Ultra clean DCC Track Power

·     Adjustable DCC Track Voltage

·     Opto-isolation and thermal protection for Safety

·     Short and overload protection

·     Designed to meet NMRA RP-9.1.2 Power Station Interface requirements 
Includes RP-9.3.1 cutout device

The LV102 includes an powerful internal 5 amp power station. that provides clean and safe DCC power to the track. New circuitry has been developed to reduce noise, which provides exceptionally clean power to operate your DCC equipped trains.

Technical Data

Power supply
(input voltage)

with AC:                                min. 14 Volt, max. 19 Volt

with DC:                                min. 14 Volt, max. 24 Volt

When powered with a DC power source, select an input voltage which is approx. 2-3 Volts higher than the selected DCC track voltage. When powered with an AC transformer, select an input voltage that is about the same or slightly lower then the selected DCC track voltage. This avoids unnecessary loss of heat in the device which in turn could lead to an early thermal switchdown.

Output voltage (track voltage)

Settable between 11V and 22V in steps of 0.5V.  Under load the actual DCC track voltage will be slightly lower. The factory voltage setting is 16V.

Output current

The output current is limited to a maximum of 5A.

Depending on the transformer used, as well as its voltage and the set track voltage, the long term continuous current, which the LV102 DCC Power Station of the LV102 can supply, varies.

Example: When using the FCI FDA120-150-5000 transformer and a track voltage of 16V, the long term continuous current is approximately 4.4A.

Overload protection


Thermal overload protection. The switching off of the overload occurs after approx. 100ms in case of constant overcurrent (e.g. short-circuit).

Opto-isolated (Current) Interface

The LV102  uses the Opto-isolated (Current) Interface and consumes 10ma on  the Power Station Interface.


Per NMRA PR-9.1.2 The K terminal output and D terminal input represent the DCC positive polarity.
